In the past, we used to go to the store on the weekends and 'stock up' as my wife puts it. We would buy stuff in anticipation of making meals, yet it never failed that something would go unused and end up going bad. Or a high yield dish would be cooked that didn't turn out so well and shoved into the freezer for months.
Now that I'm unemployed, I balk at the notion of 'stocking up'. There is a grocery store 2 blocks from the house and I've gottent into the habit of walking there almost daily. Though I don't think I'm really saving any money by doing so, I also feel that I'm not wasting as much either.
